None of the code here seems anything to do with loading properties files. If you're in an applet they you won't have permission to set the security manager.

14. ResourceBundles properties files

I'm reading about internationalization with properties file backed resource bundles ( on the java web site ). It appears that resource bundles and properties files were meant for i18n. Does this mean that when people use properties files to parameterize their applications, as is very common, that its a bit of a misuse of the resource bundle?

15. why do we need to recompile our project when its property files are change?

And, as already mentioned, if that is the only one you change, then the next time you recompile your project those changes will be lost. Go into the project properties in Eclipse and reactivate the automatic compilation. Then you need only change the "source" version of the properties file, and Eclipse will update the one in the compiled area automatically, which ...

Well the file meta data (like title/comments etc) on XP is saved into alternate data streams (ADS) with support from the underlying file systems NTFS.

43. Property files

you're missing the fact that Properties ( which are based on HashTables ) are not sorted. there's no way to guarantee the order in which the entries are pulled out. you obtain the entries by asking for them by name. there's no need for them to be in any order, if you think about it

Check the docs for System.getProperties. Maybe one of the properties it lists is the directory that the executable is in. But I'd advise doing it a different way.
